插件

Extension Pack for Java 会包含其他的插件
Getting Started with Java in VS Code

默认是提示要安装 jdk
Java 17 or more recent is required to run the Java extension. Please download and install a recent JDK. You can still compile your projects with older JDKs by configuring ‘java.configuration.runtimes’

指定特定的jdk, 在设置里进行搜索

{"java.jdt.ls.java.home": "/home/wxg/lang/jdk8/"}

设置成功后, 会在插件页提示 This extension is enabled globally., 代码也有相应的标志
